Excerpts from the Preface: This publication compiles summaries of over 20 published, academic journal articles related to agricultural transportation research. The focus is on recent research, spanning roughly the last 6 years, from 2015 to 2020. The compendium’s primary goal is to spotlight the main findings and methods of recent peer-reviewed agricultural transportation research in an easy-to-read, accessible format. The Compendium sections are structured around specific modes of transportation, as follows: • Section I covers multimodal and supply chain research. • Section II summarizes inland (barge and lake) water transportation research. • Section III summarizes marine (ocean and port) water transportation research. • Section IV summarizes truck research. • Section V contains summaries of U.S.-focused rail research. • Section VI concludes the compendium with summaries of Canadian rail research.
